The Nocebo Phenomenon (book by Fonnie DeCoster)

"The Nocebo Phenomenon," by Fonnie DeCoster, explores how negative expectations can lead to real adverse health effects. When people believe a treatment or environment will cause harm, their anxiety or stress can trigger symptoms or worsen their condition—similar to a placebo effect but in a harmful direction. This demonstrates the powerful mind-body connection and highlights the importance of framing information positively to minimize unintended negative outcomes. The book emphasizes understanding psychological influences on health, encouraging awareness of how thoughts and beliefs can directly impact physical well-being.
